Application Development is the development of new applications which may be mainframe, server, network-based, web-based or a combination

and may require interfaces to existing applications.

Application Maintenance and Support

Application Maintenance and Support includes troubleshooting, modifying, maintaining, improving security, and enhancing legacy systems and

applications which may be running in a production environment.

Technology Upgrade, Migration, and Transformation

Technology upgrade, migration, and transformation may be accomplished by converting/migrating legacy applications to new technology,

either with or without new business functionality. It may also include introducing new technology into the enterprise and managing any changes

as a result of the introduction. Transformation may include assessments of the current application portfolio, evaluation of the technology

assets before beginning technology transformation and Business Case development for justification of an initiative. Part of the transformation

journey may include planning, analysis, requirements development, proof of concept, deployment, implementation, integration, remediation,

data migration, documentation, application programming and support services, and training support.

Enterprise Resource Planning (ERP)

ERP is an amalgamation of an organization’s information systems designed to automate and integrate a variety of functions, commonly referred

to as “back office”, including financials, human resources and asset management. These systems are usually modularized and generally highly

configurable. Business Process Reengineering (BPR), system or application changes, implementation, conversion services, and training are often

included in an ERP initiative.
